SYRINGDNOZZLE.

SPECIFICATION forming part of Letters Patent No. 697,412, dated April 8,1902. Application led December 24, 1901. Serial No. 8'7,IO0. (No model.)

T0 all whom, it may concern:

Be it known that LROBERT LowEY MCMUR- VRAN, a citizen ot' the UnitedStates, residing` at Portsmouth, in the county of Norfolk and State ofVirginia, have invented new and useful Improvements in Syringe-Nozzles,of which the following is a specification.

This invention relates to syringe-nozzles, and has for its object toprovide a device of the character referred to which shall be eX-tremelysimple and inexpensive in construction and which will operate tothoroughly irrigate and wash out the vaginal canal, which may be readilytaken apart for the purpose of cleaning the device, and in which thefluid employed for irrigating the vagina will be equally distributedthrough all the perfo rations in the irrigator.

To these ends my invention consists in the features and in theconstruction, combination, and arrangement of parts hereinafterdescribed and particularly pointed out in the claims following thedescription, reference being had to the accompanying drawings, forming apart of this speciiication, where- 1n- Figure l is a side elevation of myim proved irrigator. Fig. 2 is a longitudinal sectional view thereof.Fig. 3 is a transverse sectional view taken on line 3 3 of Fig 1, andFig. 4 is a detailed perspective view of the core removed.

Broadly, my invention comprises an outer perforated cylinder provided atone end with a perforated cap and at its other end with a nipple adaptedto be connected' with the ordinary and usual 'compressible bulb orfountain and an inner imperforate core or cylinder concentrioallyarranged within the outer perforated cylinder in such manner as to leavea confined space between said core and outer cylinder, whereby thepressure of the liquid supplied to the irrigator is equalized throughoutevery part of the latter and the cleansing fluid is equally distributedthrough all the perforations.

Referring to the drawings, l indicates a hollow cylinder provided withnumerous perforations 2. As shown, the perforations formed in thecylinder are inclined rearwardly for the purpose hereinafter explained.The

cylinder may have a smooth periphery, if so desired; but preferably itis longitudinally corrugated, as shown, and the perforations arepreferably formed in the grooves between the ribs forming theeorrugations. The opposite ends of the cylinderl are internallythreaded, as at 3, and screwed into the rear threaded end is a nipple 4,adapted to be inserted in one end of a tube, the other end of which maybe connected with the usual and ordinary compressible bulb or fountain.(Not shown.) In the other or forward end of the cylinder is screwed ahollow cap 5, rounded externally, as shown, and provided with aplurality of perforations 6.

Disposed within the hollow cylinder 1 is a cylindrical core or cylinder7, rounded at its opposite ends, as indicated at 8 and 9, said corebeing of slightly less' diameter than the internal diameter 0f cylinderl. Arranged on the periphery of said core near its opposite ends are twoannular series of projections 10, which project a sufficient distancebeyond the periphery of the core to loosely engage the interiorofthecylinderl. Saidprojectionsoperate to center the core within theperforated cylinder and hold it concentrically therein in such mannerthat a uniform annular space will intervene between the periphery of thecore and the interior of the cylinder. In like manner projections 1l areformed on or xed to or in the forward end 9 of the core and abut theinner end of the cap and prevent the end of said core from seating inthe inner end of said cap and closing the perforations there# 1n.

For the sake of lightness and economyk the core is preferably madehollow and of any suitable light and thin material. I have shown theprojections on the coreas consistving of smallpins or pegs, that areinserted in the periphery and in the forward end of the core, and forthe sake of cheapness of mannfacture this is the preferred arrangement;but it will be manifest that the projections may be formed in variousdifferent Ways and either attached to or formed integrally with thecore.

The entire device may be made of any suitable substance-such, forexample, as vulcanized rubber or celluloid or any material that issufficiently light and not affected by the action of water or the usualcleansing compounds employed for treating the Vagina.

The operation of my improved irrigator is IOO as follows: The partshaving been assembled in the manner described, the nipple is insertedwithin the end of the tube leading to the compressible bulb or fountainand the irrigator is inserted in the vaginal canal, as usual. The waterforced into the irrigator from the bulb or fountain is spread by thecore and is forced through the confined space between the interior ofthe cylinder and cap and the core in a thin sheet and is distributedwith uniform pressure to every part of the interior of the cylinder andcap and is forced out through the perforations therein with uniformpressure. The corrugations in the periphery of the cylinder operate todilate the membranous lining of the vaginal canal, and the groovesbetween the ribs forming the corrugations act as ducts for conveyingolic the liquid to the mouth of the vagina. By inclining theperforationsin the cylinder backward, as shown, the water or cleansingrfluid discharged through said perforations is directed backward oroutward toward the mouth of the Vagina to facilitate its discharge andto more thoroughly wash out the vaginal canal. By screwing the nippleandthe cap in the outer cylinder and by loosely arranging the coretherein in the manner shown and described the parts may be quickly andconveniently taken apart for the purpose of cleaning them, so that theparts may be readily and thoroughly cleansed before and after using thedevice. As before described, the projections on the periphery of thecore maintain every part of the periphery of said core equidistant fromthe interiorof the perforated cylinder, and the projections (one ormore) on the end of the core prevent the water from forcing said end ofthe core against the inner end of the cap, whereby said core cannot seatitself in the cap and close the perforations therein.

Having described my invention, what I claim is- 1. A syringe-nozzlecomprising an outer perforated cylinder and an inner imperforate core ofsmaller external diameter than the internal diameter of said cylinderand arranged concentrically within the latter, substantially asdescribed.

2. A syringe-nozzle comprising an outer perforated cylinder and an innerimperforate core of smaller external diameter than the internal diameterof said cylinder and arranged concentrically within the latter, andmeans for maintaining every portion of the periphery of said core at auniform distance from the interior of said cylinder, substantially asdescribed.

A syringe-nozzle comprising an outer hollow cylinder provided with aplurality of perforations inclined rearwardly and an inner imperforatecore of smaller extern al diameter than the internal diameter of saidcylinder and arranged concentrically within the latter, substantially asdescribed.

et. A syringe-nozzle comprising an outer perforated cylinder provided atone end with a perforated cap and at its other end with a nippleforintroducing the cleansing fluid into said cylinder, and an innerimperforate core of smaller external diameter than the internal diameterof said cylinder, and of less length than said cylinder, said core beingarranged concentrically Within the cylinder, and means for maintainingevery part of the exterior' of said core out of contact with theinterior of the cylinder and its cap, substantially as described.

5. A syringe-nozzle comprising an outer perforated cylinder and an innerimperforate core of smaller external diameter than the internal diameterofsaid cylinder, and arranged within the latter, and projections on theperiphery of said core arranged to loosely engage the interior of thecylinder and hold said core concentrically within the cylinder,substantially as described.

G. A syringe-nozzle comprising an outer perforated cylinder, provided atone end with a perforated cap and at its other end with a nipple for theintroduction ofa cleansing fluid, of au inner imperforate core ofsmaller cX- ternal diameter than the internal diameter of said cylinderand arranged within the latter and laterally-projecting pegs fixed inthe periphery of said coro and loosely engaging the interior of theperforated cylinder, said pegs operating to hold the core concentricallyin the cylinder, substantially as described.

7. A syringe-nozzle comprising an outer perforated cylinder, provided atone end with a rounded perforated cap and at its other end with a nipplefor theintroduction of acleansing Huid, a hollow inner imperforate corerounded at its opposite ends, and of less length and diameter than theinner dimensions of the cylinder and cap, and projections on theperiphery and forward end of said core for holding the latter out ofcontact with the interior of both the cylinder and cap, substantially asdescribed.

S. A syringe-nozzle comprising an outer perforated cylinder internallythreaded at its opposite ends, a hollow rounded, perforated cap screwedin one end of said cylinder, a nipple for the introduction of acleansing fluid screwed in the opposite end of said cylinder and aremovable imperforate core, rounded at its opposite ends, and of lessdimensions externally than the internal dimensions of said cylinder andcap and removably arranged Within said cylinder, and projections on theperiphery and forward end of said core for holding the latter out ofcontact with the interior of the cylinder and cap, substantially asdescribed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
